Appendix II. Banking Sector Stress Testing Matrix (STeM)
Banking Sector: Solvency Risk Domain Assumptions Top-Down by Authorities Top-down by FSAP Team 1. Institutional Perimeter Institutions included • 8 banks (5 D-SIBs and 3 IRB banks) and 3 specialized financial institutions. • 8 banks (5 D-SIBs and 3 IRB banks) and 3 specialized financial institutions (using a similar approach). Market share • Banks representing 75 percent of banking sector assets. • Banks representing 75 percent of banking sector assets and SFIs representing 95 percent of SFI sector. Combined accounting for 80 percent of bank+SFI sector. Data and baseline date • Supervisory reports at June 2018. • Data on a ‘solo consolidated’ (banking group level). • PD/LGD/EAD data for IRB banks. • Supervisory reports as of June 2018. • Data on a ‘solo consolidated’ (banking group level). • PD/LGD/EAD data for IRB banks. 2. Channels of Risk Propagation Methodology • In-home macro-ST framework (balance- sheet model). • IMF Solvency Stress Test Workbox (balance-sheet model). Satellite models for macrofinancial linkages • In-home satellite models for: o ‘Group 1’ variables, dependent on macro factors (effective lending and borrowing rates, effective rate on bonds, loans and liabilities’ growth, equity holdings); relationships with macro factors estimated via VAR, OLS, dynamic panel regressions. o ‘Group 2’ variables, dependent on group 1 variables (bond holdings at market price, fees and commissions, non-interest expenses and non-interest-earning liabilities); relationships with macro factors estimated via OLS. o ‘Group 3’ variables, whose calibration is based on expert judgment (other non-interest income and net open position in FX). • Seemingly unrelated regression of NPL inflow rates, by economic sector, on macro variables. • System-wide regression of credit growth as a function of domestic demand and unemployment (with a judgmental floor to prevent excessive deleveraging), growth of capital determined endogenously within the workbox, growth of liabilities obtained residually. • Pre-impairment income estimated piecewise: panel data estimation of banks’ effective interest rates on loans, bonds, and deposits; loan and deposit growth based on system-wide forecasts; historical evidence for non- interest-income items, coupled with judgmental adjustments to factor in increasing competition on banking services. 44 INT ER NA TIO NA L MO N ET AR Y F UN D |
